Specification of Letters Patent.

Patented July 111, 1911.

Application filed November 10, 1909. Serial No. 527,128

To all whom it may concern:

Be it known that I, SAMUEL "W. FISH, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Compound Safe or Vault Doors, of which the following is a specification.

The present invention relates to safe or vault doors, the object of the invention being to provide an improved compound door made up of a plurality of doors rigidly secured together in an improved manner for movement as a single structure, each of said doors being a complete door in itself, however, so that the separation of one door from the other will not only require the rupturing of the holding means between the doors, but also the locking means between the outer door and the jamb of the safe body, the present improvement being an improvement in part on that shown and described in my contemporaneously pending application, Serial No. 492,869, filed April 29, 1909, and in my other co-pending applications, Serial No. 526,4t86, filed November 6, 1909, Serial. No. 527,125, filed November 10, 1909, and Serial No. 527,126, filed November 10, 1909.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear view of this improved door; Fig. 2 is a cross-sectional view thereof, taken in line 22, Fig. 1; Fig. 3 is a rear view, partly broken away, of the front door; Fig. 4t is a cross-sectional view taken in line M, Fig. 3; Fig. 5 is a front view, partly broken away, of the rear door; and Fig. 6 is a cross-sectional view taken in line 6-6, Fig. 5.

Similar characters of reference indicate corresponding parts throughout the figures of the'drawings.

The present improvement comprises a pair of doors, each preferably of an integral structure and each a complete door in itself, one, or the rear door, designated in a general way by A and the other, or the front door, designated generally by B.

The rear door comprises a body rearwardly extending flange 3 having bolt openings 4c provided therein, which openings, when the door is made of uninachineable metal, such as manganese steel, are provided with soft metal inserts 5 to facilitate 2 and a the machining of the bolt openings for the reception of the bolts which may be used for locking the door against rotation when the door is made as a rotary door and to lock it against withdrawal when the door is made other than as a rotary door. The front door B also comprises a body 7 having a rearwardly extending flange 8 likewise provided with similar bolt openings 9, the locking means for securing the door in the jamb thus being in duplicate.

For securing the doors rigidly together an lmprovod means is provided, this being shown in the present instance as of dovetail formation, so that one door is united to the other door by the sliding movement of one relatively to the other transversely of the axis thereof. In the present instance the rear door is provided with a pair of dovetail-formed projections 12 located on the front thereof adjacent to the periphery, while the rear face of the front door is provided with similarly formed recesses 13 for engagement with the dovetail projections of the rear door, the two doors being thus united by sliding one door cross-wise of the face of the other, that is, transversely of the axis thereof, so that the doors are very firmly and securely united for move ment together as a single structure.

For preventing the displacement or movement of one door relatively to the other suitable keys 15 may be provided fitting slots formed in the front face of the rear door and the rear face of the flange of the front door. The two doors thus united have a continuous joint surface coned or tapered for engagement with the jamb surface of the body, and by reason of the flange of the front door having a chamber therebetween for the reception of suitable means for operating the bolts adapted to be pro jected through the bolt openings in such flange these bolts may be operated by a straight spindle similar to that shown and described in my co-pending application Serial No. 527,125, filed November 10, 1909.

By the provision of a compound door of the character set forth I am thus enabled to use a straight spindle instead of a tapered one, since the same can be inserted in position from the rear face of the front door prior to the doors being united by their dovetail locking means. The bolts of the rear door may be operated by an automatic or any other suitable form of bolt retracting and protracting means, as may be found most desirable in practice.

It will thus be observed that, in order to effect an entrance into the safe, not only must the outer or front door be removed, but also the inner door, and as each is secured in position by its own locking means this improved structure provides a safe or vault door which is practically impregnable, since even though the front door should be removed by a burglarious attack the inner door is still securely locked and forms therefore a safe which has all the strength and resisting qualities of the ordinary safe provided with a single door.

I claim as my invention:

1. A safe or vault door comprising a rear door and a front door rigidly connected for movement as a unitary structure by dovetail interlocking means a part integral with each door and extending partway only across the doors.
